ABSTRACT:
A method for making triniobium tin foil is disclosed where the niobium-based foil with an oxide layer is passed continuously at a set speed into an enclosed chamber. The enclosed chamber has an inert atmosphere which is substantially oxygen free. Upon entering the chamber, the foil passes through a decomposition anneal furnace, a low temperature tin dip, and then a high temperature reaction anneal furnace before exiting the chamber as triniobium tin foil.
